Cuspidor



Patented Nov. Z6, 1929 UNITED STATES LAUD E. RUF, OF SAN JOSE,CALIFORNIA CUSPIDOR Application led February 14, 1929.

It is the objectof the present invention to provide a cuspidor that willat all times present a clean and neat appearance to the eye of thebeholder, and one that may be quickly and easily disassembled foremptying and cleaning, and as quickly and easily reassembled for use.

It is also an object of the invention to provide a device of thecharacter indicated that l@ will be economical to manufacture, simple inconstruction, and highly eliicient in its practical application.

In the drawing, the ligure shows a vertical transverse section through acuspidor embodying my invention.

Referring now more particularly to the drawing, I show at 1 a bowl ofany suitable material and size and fitted with a drain at 2. In thecenter of the bottom of the bowl is mounted a threaded ferrule 3 havinga water supply pipe screwed into its bottom as at 4. In the upper edgeof the bowl is formed an annular groove as shown at 5, and a conduit 6is shown communicating with this f groove and with a water supply pipeas 7.

At 8 is shown an annular rim threaded on to the bowl 1 and having aconduit 9 formed therein as shown. A small passage is 'formed in the rimas at 10 to connect the conduit 9 with the groove or channel 5 when therim is secured in position on the bowl. Formed on the inner and loweredge of the rim 8 is a depending and inwardly extending flange 11carrying a dish-shaped annular member 12 having a central opening 13formed therein.

The rim 8 also has an overlying annular lip 111 formed upon its upperpart and curving inwardly over the dish-shaped member to form a channel15. At 16 are shown a number of small orifices communicating with theconduit 9 and discharging into the channel 15.

A cone-shaped element is shown at 19 mounted on a stem 17 having apassage 18 therethrough and screwed into the top of tei-rule 3. Thiscone shaped member is some- Serial No. 339,794.

what larger in diameter than the opening 13 in member 12, and the stem17 is of such a. length as to support the element 19 over the opening 13and overlying the member 12.

In the bowl 1 is placed a removable screen 18 adapted to seat in thebowl and receive such refuse as may pass into the bowl through theopening between the cone 19 and element 12.

When the device is assembled as hereinbefore set forth with the supplywater pipes 4 and 7, a constantflow of water is maintained over the topsurface of the coneshaped member 16 and over top surface of the member12, the water discharging on to the latter surface through the orifices16 from conduit 9. This constant How of water of course keeps thesesurfaces clean all waste being carried down into the bowl 1 where thewater and all liquid is discharged at the drain 2. To clean the interiorof the bowl it is only necessary to shut off the liow of water and thenunscrew the stem 17 and then the rim 8. This exposes the entire insideof the bowl so that the screen 18 with its more or less solid contentsmay be removed.

It is to be understood, of course, that while I have herein shown anddescribed but one speciic embodiment of the invention, changes in form,construction, and method of assembly and operation may be made withinthe scope of the appended claims.

I claim:

1. A cuspidor comprising, a bowl having a groove formed in its upperedge having a water supply pipe communicating` therewith, a rim disposedon the bowl to overlie the groove and having a conduit formed thereincommunicating with said groove and having a plurality of orifices formedtherein communicating with the conduit and the interior of the rim, adished member disposed to receive the water discharged through theorilices and having a central opening therein, a cone shaped member ofgreater diameter than said opening axially disposed in the bowl,

and means for discharging a flow of Water gver the Joop surface of thecone shaped mem- 2. A ouspidor comprising, a bovvl, a dished capremovably mounted thereon and having an opening formed in its center,means for discharging Water over the dished cap, a cone shaped memberconcentrically mounted relative to the dished cap and having a diametergreater than the diameter of the opening in the dshed cap and spacedagdistance from said cap, andlmeansffor discharging Water over the topofthe cone shapedmember.
